squid -k reconfigure doesn't work?

I run "squid -k reconfigure" but nothing happens. The old
configuration keeps running and if new acl's are added they look to be
ignored. I'm using Squid in Solaris 9 and when I monitor through the
'prstat' command (equivalent to 'top' in Linux) squid cpu ussage stays
constants (around 7%).

Does anyone have simmilar problems?

Thanks in advance for any hint!
